Ben Stiller is famous for having three - count 'em - billion-dollar franchises to his name and one of them, Night At The Museum, is gearing up for a third instalment. Today's news is that Rebel Wilson has joined the cast. Deadline reports that Australia's comic actress of the moment will be coming off all Pommie to play a night guard at the British Museum.

This news further confirms the rumour that Stiller and director Shawn Levy would be bringing their comic shingle over to these shores. With Daniel Stevens playing Lancelot and Robin Williams back on board as President Teddy Roosevelt, there's plenty of scope for a big cross-cultural hoedown. Just add Winston Churchill, Lord Lucan, Herman's Hermits, Hamburglar, The Fonz and Ichabod Crane and we're away.

The third Museum movie has been scripted by Thomas Lennon, Robert Ben Garant, David Guion and Michael Handelman, and should be underway in the next month or so with a lucrative Christmas holiday release date pencilled in by 20th Century Fox.

Wilson, meanwhile, has been busy making a name for herself in Pitch Perfect and Bridesmaids. She also popped up in Pain & Gain and will also be sequel thing in Pitch Perfect 2.
